Browning Invector-Plus Diana Grade Extended Choke Tube, 12 Gauge: Improved Modified

Titanium nitride for durability and hardness. Optimal patterns for Invector-Plus 12 gauge shotguns. A complete selection from Spreader to Full is available. Not an ordinary choke tube.

The Gold Standard for choke tubes. The longer choke taper inside Diana Grade Invector-Plus choke tubes improves pattern performance. These tubes are for use with back-bored barrels on 12 gauge shotguns. They offer a superior construction from stainless steel bar stock that is heat treated prior to machining. The use of a titanium nitride surface with 72HRC hardness provides excellent wear and reduced plastic buildup, and they look beautiful on the muzzle end of your Browning Citori.
